Before these recent changes, you had 5000 characters to play with but now you have 250. It’s not all bad though and it’s a level playing field.
From initial testing I have found the below points to be true:
1.Amazon is now indexing back-end keyword fields for a maximum of 250 characters.
2.YES, I hear you 250 total and that’s across ALL back-end keyword fields and not 250 per field.
3.The 250 character limit is not including spaces but it will count commas so don’t include them.
4.If you exceed 250, then the search term field is ignored and that includes the first 250 characters.
5. keywords in the title and bullet are still getting indexed and the title has the biggest impact.
